Why Choose the Carlo Gavazzi S142BRNT115 Photoelectric Amplifier?

The Carlo Gavazzi S142BRNT115 is a versatile single-channel photoelectric sensor amplifier with timer functionality designed for reliable object detection and timed switching in industrial automation, machinery and material handling systems. As part of the Carlo Gavazzi S142 series, it is designed for compatible through-beam photoelectric sensors and supports sensing distances of up to 50 m.

The S142BRNT115 combines adjustable sensitivity, diagnostic functions and alignment assistance with an integrated time-delay function. This allows the amplifier to provide controlled delayed switching in addition to conventional photoelectric detection, making it particularly useful where detected objects need to initiate timed machine or process functions.

Designed for a nominal 115 V AC supply, with a rated supply range of 98–132 V AC, the amplifier provides an NPN transistor output and SPDT relay contact. Selectable light-on and dark-on operation, an 11-pole plug-in connection and a compact socket-mounted housing provide flexible integration into industrial control systems.

Key Advantages

  • Industrial single-channel photoelectric amplifier with integrated timer.
  • Supports through-beam sensing distances of up to 50 m with compatible sensor heads.
  • NPN transistor and SPDT relay outputs provide flexible control-system integration.

Timed Through-Beam Detection for Industrial Automation

Through-beam photoelectric systems use separate emitter and receiver sensor heads positioned across a detection area. When an object interrupts the transmitted light beam, the amplifier changes its output state, providing reliable non-contact detection over substantially longer distances than many diffuse-reflection sensing arrangements.

The S142BRNT115 adds an integrated timer to the sensing and amplification functions of the S142 platform. Its adjustable 0.1–10 s time delay, long sensing capability, configurable light-on or dark-on operation and combined NPN and SPDT outputs make it suitable for applications requiring both reliable object detection and controlled timing of downstream equipment.

Typical Applications

  • Industrial conveyors and material handling systems.
  • Long-distance through-beam object detection.
  • Timed product presence and position monitoring.
  • Packaging and production machinery.
  • Automated doors, gates and access systems.
  • Industrial assembly and processing equipment.
  • Warehouse and logistics automation.
  • OEM machinery requiring photoelectric detection with time-delay control.
